Chainsaw users face the inevitable time when they need to sharpen their chains. This can be very tedious if done with a hand file. This is where benchtop grinders come in. They make the sharpening process much easier and more efficient. Oregon offers the 620-120 as a powerful option. We will evaluate it based on project needs.

When compared with the Oregon 520-120, both grinders offer the same speed motor and similar performance. However, the 620-120 features more control features, allowing for more precise sharpening than the 520-120.
Universal Chain Sharpening
The Oregon 620-120 features universal chain sharpening. It can sharpen almost any chain, supporting up to a 0.404-inch pitch.

Vise Attachment
This grinder features a hydraulic piston that squeezes the chain vise for maximum efficiency. Also, when the wheel and motor are both lowered, there is a hydraulic assist that closes the vise automatically. Because the clamping vise is hands-free, it allows for even faster grinding. Additionally, the chain vise is self-centering, allowing for the most precise grinding.
The vise attachment is standard, fitting to sharpen most chainsaw chains. It has a large indexing chain stop feature. This works on a large surface area to accommodates a variety of chains.
